Methodology: How Is Your Water Bill Determined?

With water costs climbing to eye-watering rates, it’s more important than ever to understand how your water bill is being calculated. When you’re hit with higher water charges, you want to make sure you get what you pay for.

Average Monthly Water Bill in the United States

Water Usage

Fixed Rate: For the vast majority of US citizens, your water bill will be determined by how much water you use. But occasionally you’ll encounter utility companies offering a flat rate for water, regardless of usage.

As of 2021, a number of electricity suppliers are using this model to offer fixed-rate energy charges, but for now it’s relatively rare in the water industry. Suppliers find it hard to maximize profit under this model, and it hardly encourages efficient use of water when there’s no penalty for leaving the tap running!

Flat Rates: It’s more common for water companies to charge by the gallon. And sometimes this is as simple as it sounds – your water costs grow in a linear way, depending on how much water you consume. With a uniform rate, you know that every gallon costs the same as the last, so it’s easy to calculate what you’ll owe – and if you can afford that bath at the end of the month!

Unfortunately, it’s not always as simple as 1 + 1 = 2! Water companies use a range of complicated pricing models to encourage particular consumer behavior. Increasing or decreasing block rates are the most common.

Increasing Block Rate: If you have an increasing block rate calculating your tariff, water gets more expensive, the more you use. For example, you could be charged at $1/gallon for the first hundred gallons you use – and then $1.50 for further water consumption.

In areas where water is scarce – particularly urban zones – increasing block rates are used to discourage excessive water consumption. If you’re on one of these plans, think carefully before you decide to fill the paddling pool!

Decreasing Block Rate: Although less common in urban areas, decreasing block rates are commonly found in rural areas where agricultural habits demand a lot of water. A decreasing block rate charges less per gallon once you start using a lot of water. For example, water might start at $1/gallon – and drop to $.75 after one hundred gallons, and $.50 after one thousand.

For city dwellers, it’s counterintuitive – but where water is plentiful this is a mechanism to allow water companies to make their profits without heavily penalizing those with higher water needs.

Local Cost of Water

Once you understand the rates water can cost, you’re one step closer to calculating your water bill. The local cost of water will be the final factor in determining what you pay.

Local water costs will vary from state to state or even from one zip code to the next. And they’re not stable all year round either. Seasonal fluctuations in supply might cause your utility company to charge more for water all summer long, whereas a sudden drought can cause water prices to spike.

And all across the United States, water prices are rising. The EPA now estimates that the average household water bill is over $1000 annually. Let’s take a closer look at the cost of water across the country.

Ways To Cut Your Water Bill

Water charges vary radically across the United States, but wherever you are there are ways to save. Even in states with affordable water, it’s worth tightening your belt when it comes to your utilities.

Few people have a choice over their water provider – that means you can’t shop around for a better deal. Instead of this consumer tactic, here are some top tips for reducing your water bill to a trickle.

Shorten Your Showers

Across the United States, showerheads are limited to a water pressure of 2.5 gallons per minute – this is an industry-standard water-saving measure. But 2.5 gallons is still a lot of water – in fact, it’s more than you’d drink in two days.

Long showers are one of life’s great luxuries but don’t zone out in the shower. Every minute is adding dollars to your water bill.

Fix Leaky Faucets

A leaky faucet might seem like a drop in the ocean – but multiply that drop by minutes, hours, and days. Learning to see leaky faucets, showerheads, washing machines and toilets as money down the drain – get leaks fixed as soon as you spot them.

The Environmental Protection Agency (EPA) estimates that a showerhead leaking ten drips per minute can waste over 500 gallons a year. Wasting water hurts your wallet.

Upgrade Your Appliances

According to the EPA, you could reduce your water usage by 20% by upgrading to water-efficient appliances and fixtures. If you’re on a flat rate water plan, that’s 20% savings right away.

The EPA launched the WaterSense partnership scheme to help brands advertise their green credentials. From home water filter systems to washing machines, look out for the WaterSense logo.

Water Cost FAQ

Have you got a burning question about the cost of water? Let’s find out and blow off some steam.

Which State Has The Highest Average Water Bill?

West Virginia has the highest average water bill in the United States coming in at $91 each month. The mountainous terrain of West Virginia makes water provision an expensive business across the state.

Which State Has The Cheapest Average Water Bill?

How Much Water Does A Family Of Two Use?

Based on average water consumption, a family of two will use around 200 gallons of water every day, or 6000 gallons a month. That adds up to one Olympic-sized swimming pool every year. Going for gold?

What Uses The Most Water In A Household?

Taking a bath is the biggest culprit for water consumption in any household. A single bath uses between 40 and 80 gallons of water. That’s the same as a 20-minute shower or three loads in the washing machine!

But for many households, simply flushing the toilet will be the biggest consumer of water. Federal law limits a toilet flush to 1.6 gallons: 1.6 gallons per flush and six flushes a day, for a family of four, equates to over 40 gallons of water down the drain.

How Much Water Does A 20 Minute Shower Use?

Showerheads have a federally mandated maximum flow rate of 2.5 gallons per minute (GPM). At this maximum rate, a 20-minute shower can use a whopping 50 gallons of water!

In reality, the average flow rate for a showerhead is closer to 2.1 GPM. A 20-minute shower will use an average of 42 gallons of water.

How Can I Reduce My Water Bill?

The number one way to reduce your water bill is to reduce your water consumption. Shorten those showers, fix leaky appliances, never run a half load of laundry, and upgrade your dishwasher to an energy-efficient model.


Whether you’re splashing about in cheaper water states such as Florida or ruing water price rises on the West Coast, you have to understand your water bill. As water prices rise faster than inflation, we’re all spending more than ever on our daily water needs. 

Water is a basic human need, and from showers to hydration, we consume a lot of it going about our day-to-day.

But in this life, nothing comes for free. Managing your water bill is something everyone needs to face – and when it’s time to tighten your belt you can save a few cents by tightening the faucet as well.

Don’t get caught in the rising tide of water bills – reduce your water consumption and understand your water bills to stay afloat.
